FIELD OF THE DISCLOSURE

This disclosure relates to PANEL WIRE SUPPORT. More particularly, this disclosure relates to improved systems and methods for supporting, protecting, organizing, and labeling electrical cables and/or wires, to facilitate proper connection of those cables or wires to an electrical panel.

BACKGROUND OF THE DISCLOSURE

Electrical panels, also known as main service panels, electrical main enclosures, or breaker boxes, are found in residential, commercial, and industrial structures. Electrical panels provide a primary connection point for electricity supplied to the structure from an electrical utility, and contain numerous breakers and individualized terminations for electrical cables or wires. The cables or wires often take the form of non-metallic sheathed cables (NM and NMC, also known as Romex-type cables, and SER cables) which are often found in residential structures, or of conduit-protected cables which are often found in commercial and industrial structures. In some situations, other cables, such as fiber optic cables, may be supported. Examples of electrical panels and various non-metallic sheathed cables and/or conduit-protected cables are disclosed in U.S. Patent Nos. U.S. Pat. No. 5,784,249; U.S. Pat. No. 7,381,907; U.S. Pat. No. 7,405,923; U.S. Pat. No. 7,616,432; and U.S. Pat. No. 702,198.

The most common panel wire support found in many structures in the United States is a 2×6 or a 2×4 that spans the distance between two studs, approximately 12-inches above an electrical panel suspended between those two studs. The 2×6 (or 2×4) is oriented with the longer dimension running parallel to the corresponding wall, and cables, wires, and/or conduit are stapled to the exposed larger face of the 2×6 (or 2×4). Examples of specific wire supports are disclosed in U.S. Patent Nos. U.S. Pat. No. 6,996,943 and U.S. Pat. No. 8,505,858, and U.S. Patent Application Publication No. US20170063064.

In new construction, a popular method for supporting wires is to cut a 2×6 (or 2×4) piece of wood to a length equal to the width of an electrical panel and toenail (affix with nails driven in at an angle) said piece of wood between the studs 12-inches above the electrical panel. A worker can then lay cables and/or wires over the top of the length of 2×6 (or 2×4) and individually staple the cables or wires to the piece of wood. Problems with this method include the time and effort involved, and possible damage to the cables and/or wires before they reach the panel. In addition, this method does not quite comply with the National Electric Code, putting the supporting of the wires against code by ¼ inch.

Other types of supports for wires, cables, and conduit are disclosed in U.S. Patent Nos. U.S. Pat. No. 2,921,607; U.S. Pat. No. 4,291,855; U.S. Pat. No. 4,440,374; U.S. Pat. No. 5,653,411; U.S. Pat. No. 5,669,590; U.S. Pat. No. 6,222,128; U.S. Pat. No. 6,313,406; U.S. Pat. No. 6,513,766; U.S. Pat. No. 6,655,644; U.S. Pat. No. 6,857,606; U.S. Pat. No. 7,301,101; U.S. Pat. No. 7,347,401; U.S. Pat. No. 7,608,782; U.S. Pat. No. 7,784,751; U.S. Pat. No. 407,963; U.S. Pat. No. 663,274; US2001/0022231; and US2007/0137888.

The disclosures of these and all other publications referenced herein are incorporated by reference in their entirety for all purposes. However, none of these other types of supports are both configured to support the large and varied collection of cables such as might need to be passed into an electrical panel and designed to be easily installed between two studs in a stud wall above an electrical panel at any desired height. For at least this reason, there is a need for a panel wire support that can be affixed easily and quickly between two studs some distance apart at some known distance above (or below) an electrical panel, that supports and holds fixed a large number of cables and/or wires without damaging them.

SUMMARY OF THE DISCLOSURE

A panel wire support is a structure that supports, protects, aligns, organizes and/or labels a collection of electrical cables or wires before they enter and/or engage with, or after they exit, an electrical panel such as those described above. The advantages of such a panel wire support may include facilitating proper alignment of the cables or wires for when they engage with the electrical panel, preventing cables or wires from bending or being displaced, and/or preventing damage to connections due to extraneous movement of the cables or wires. For these and other reasons it may be desirable or even required to provide a fixed support for cables or wires a set distance away from an electrical panel. In the U.S., it is required by the National Electric Code to support cables or wires within 12 inches of an electrical box (National Electric Code ref. 334.30).

The present panel wire support bracket is disclosed in several different embodiments. A carefully engineered panel wire support bracket fits between two studs in a stud wall, and is attached at each side to one of the studs it is mounted between. The panel wire support bracket according to the present disclosure may be molded as a single element. In some examples, a panel wire support bracket may be molded as multiple elements which are then attached together.

At either end of the main body of the panel wire support bracket are end flaps that may be hingedly connected to the main body. The end flaps are configured to be affixed to the studs between which the panel wire support is to be installed. The hinged connection allows the end flaps to flex in or out as needed depending on the distance between the studs. Each end flap has a pair of flanges for releasably engaging with the side walls of the main body of the panel wire support bracket when the end flaps are folded down to be perpendicular to the upper plate of the panel wire support bracket. This engagement helps to support and stabilize the side walls.

The panel wire support bracket is preferably mounted approximately 12-inches (12″, with ″ being used below to indicate inches) above an electrical panel in new home construction or new building construction. The body of the support bracket may be molded with visual and tactile indicators approximately 12″ from each of the end plates making such placement easy and convenient.

The top surface of the panel wire support bracket has a series of holes going from top to bottom of the bracket through approximately a 1½″ thickness. These holes are configured to accommodate, for example, individual NM and NMC (Romex-type) cables such as those discussed above. In some embodiments, the holes may be configured to accommodate MC cables, of the type more commonly used in commercial work. The individual holes in the bracket are situated in a central portion of the wall so as to keep wires at least 1¼″ from any drywall or surface layer at the front or the back of the stud wall. That is, the holes are situated substantially within a 1″ “central plane” of the wall. Wires that might otherwise have been stapled to the side of the 2×6 (or 2×6) piece of wood, are now supported approximately 12″ above the panel by inserting the wires through the individual, designated holes before terminating at the panel.

For additional support, each hole may include one or more features that increase its holding or gripping effect. The guide walls of the individual holes help to prevent the wire from being easily moved within or through the hole by random movements of the wire. In addition, each hole may include one or more protrusions formed on a flexible support. Such protrusions may be easily releasable due to an extension tab arranged such that a gap remains between the tab and any wire or cable being held within the opening. An installer may use the extension tab to pull the flexible support, and thus the protrusion, away from the wire to more easily insert or remove a wire when desired.

Some embodiments of the panel wire support bracket may include a legend area for marking the wire, so that it is easy for an installer to determine and keep track of which cable should be connected to a particular breaker or terminal. Many embodiments of the panel wire support bracket are nonmetallic, but some embodiments may be metallic or may include metallic components.

In an exemplary method of use, an electrician will hold one of the disclosed support brackets in place between two vertical studs with one hand, and use a power drill with a magnetized Philips-head screwdriver bit (for example) in the other hand. A Philips-head screw (for example) can be grabbed magnetically, after which the electrician uses the power drill to attach one end flap of the support bracket to a vertical stud within the wood frame. This may take less than 5 seconds. The electrician can then use the same process to attach the other end flap of the support bracket to the other stud, in the same fashion. The electrician will then proceed to insert several cables or wires into the holes on a top surface of the support bracket and pull the cables or wires through from a bottom of the support bracket.

Advantages of the present disclosure will be more readily understood after considering the drawings and the following Detailed Description.

DETAILED DESCRIPTION OF THE DISCLOSURE

Examples of panel wire support brackets are shown in FIGS. 1-19. Unless otherwise specified, a panel wire support may, but is not required to contain at least one of the structures, components, functionalities, and/or variations described, illustrated, and/or incorporated herein.

Overview: FIG. 1

The present disclosure relates to support brackets for use when installing electrical wiring inside building walls. As seen in FIG. 1, a support bracket 10 is molded as a single piece and includes a main body 12 with a first end 14 and a second end 16. Main body 12 also includes an upper plate 20, a first side wall 22, and a second side wall 24. Upper plate 20 includes a plurality of holes 18. At first end 14 of main body 12 is a first end flap 30 and at second end 16 of main body 12 is a second end flap 40. Support bracket 10 may include any suitable material configured to be durable and resilient and to allow for flexible hinges and guide walls. In some examples, support bracket 10 may be constructed out of any suitable materials including polypropylene or other suitable plastics, or metals such as aluminum. Support bracket 10 may be constructed using any suitable technique, such as injection molding or 3D printing techniques. Any material suitable to the proposed use in supporting electrical wiring may be used, e.g., polyethylene or polypropylene. As more specific examples the polypropylene manufactured by Flint Hills Resources of Longview, Texas as P5M6K-048 or the polypropylene manufactured by PolyOne Corporation of Avon Lake, Ohio as Maxxam™ FR PP 301 Black 1284-11 S Polypropylene may be used. The bracket may be produced in any suitable color, such as black, white, clear, or translucent. Preferably, the material is approved by UL for the intended use.

Support bracket 10 is shown in FIG. 1 installed in a stud wall 500 between a first building stud 502 and a second building stud 506. The plurality of holes and/or openings in main body 12 securely but releasably hold a plurality of cables and/or wires 510. Holes 18 (see FIGS. 2-4) may include a variety of shapes to support a variety of sizes of wires 510.

As can be seen in FIG. 1, each of end flaps 30 and 40 are hingedly attached to main body 12 by a flexible hinge 50 so that each end flap may fold down and be attached to an inner face 504 of stud 502 or an inner face 508 of stud 506 inside building wall 500. End flaps 30 and 40 have an end width EW that is equal to or larger than an upper plate width PW (see FIG. 10) and less than or equal to a width of the building studs WS. In some examples, upper plate width PW is approximately equal to 1½″ and width of the building studs WS is approximately 4″ or 6″. In some examples, end width EW approximately equals width of the building studs WS, which makes alignment of end flaps 30 and 40 with outer edges of studs 502 or 506 simple and consistent. A plurality of nail or screw holes 52 may be preformed in each of end flaps 30 and 40 so that an installer knows exactly where to attach end flap 30 or 40 to stud 502 or 506 and to prevent the extra expenditure of time and effort that may be needed to drill holes in the end flaps or otherwise modify support bracket 10 to be affixed to wall 500. Nail or screw holes 52 may include any suitable structure configured to allow attachment of support bracket 10 to studs 502 and/or 506 by means of a fastener or a plurality of fasteners. A fastener may include any suitable device configured to attach support bracket 10 to studs 502 and/or 506. In some examples, a fastener may be a nail, a screw, a rivet, a bolt, and/or any other suitable device.

The flexible hinge connections allow end flaps 30 and 40 to pivot, as discussed above, and they also allow for some variation in spacing between inner faces 504 and 508 of studs 502 and 506 respectively. End flaps 30 and 40 may tilt outwardly or inwardly to span a greater or lesser expanse between two studs. Furthermore, the flexible hinge connection allows for some compressibility in hinge 50, so that a folded configuration of support bracket 10 may be squeezed into a slightly smaller expanse between two studs. As an example of the flexible hinge accommodating variation in the spacing between two studs, studs are typically spaced at about 16″ on center, leaving a nominal space between stud faces of about 14½″ (for 1½″-wide studs). The flexible hinge typically allows installation in between stud inner faces that are at least about 14½″ apart as well as between faces that are no more than about 14¼″ apart.

In FIG. 1, support bracket 10 is mounted a distance DD above a main power panel 520 inside stud wall. Most building codes in the United States require that a support bar, such as support bracket 10, be mounted a distance above a main power panel (corresponding to distance DD above main power panel 520) that is approximately equal to 12″. As best seen in FIG. 6, support bracket 10 makes measurement of distance DD accurate and easy by including a predefined indicator 12″ from an opposite end flap. Preferably, support bracket 10 includes an indicator 26 at four locations, so that reliable measurements may be made regardless of the orientation of the support bracket relative to an installer.

Holes 18 in upper plate 20 are arranged to correspond generally to a corresponding pattern of holes used by many manufacturers of main power panels. Two different embodiments, having two different possible arrangements of holes, are shown in FIGS. 2-9 and FIGS. 10-12 respectively. Other patterns of pre-defined holes may be included in other embodiments.

First Embodiment FIGS. 2-9

FIGS. 2-9 show a first embodiment of the invention. FIG. 2 is a top perspective view of the first embodiment. FIG. 3 is a bottom perspective view of the first embodiment where one end flap is folded in and the other is folded out. FIG. 4 is another top view where the end flaps are folded out and FIG. 5 is a side view where the end flaps are folded in. FIG. 6 is a bottom perspective view that shows the distance indicators. FIG. 7 shows the guide walls of a hole. FIG. 8 is a top perspective view of a second end of the embodiment and FIG. 9 is a bottom perspective view of a first end of the embodiment.

As in FIG. 1, main body 12 includes upper plate 20 (defining upper plate width PW) and side walls 22 (visible in FIGS. 3, 5, and 9) and 24. Side walls 22 and 24 define a vertical length VL. In this embodiment, PW is approximately equal to 1½″ and VL is approximately equal to 1½″. In some examples, PW may be any suitable width and VL may be any suitable length. Upper plate 20 of main body 12 includes holes 18, each having a plurality of guide walls 60 as well as a flexible support 62 having a protrusion 64 and a tab 66.

End flap 30 is hingedly attached to main body 12 by hinge 50. End flap 30 has a stud face 32 (see FIG. 4) which is generally flat and a support face 34 which is generally parallel and opposite stud face 32. Support face 34 of end flap 30 also includes a first flange 36 and a second flange 38 each of which extend outwards from support face 34. Flanges 36 and 38 may include any suitable structure configured to couple with and support side walls 22 and 24 respectively.

End flap 40 is preferably shaped substantially identically to end flap 30 and is hingedly attached to main body 12 by hinge 50. End flap 40 has a stud face 42 (see, e.g., FIG. 4) which is generally flat and a support face 44 which is generally parallel to and opposite stud face 42. Support face 44 of end flap 40 also includes a first flange 46 and a second flange 48 each of which extend outwards from support face 44. Flanges 46 and 48 may include any suitable structure configured to couple with and support side walls 22 and 24 respectively.

In FIG. 2, end flaps 30 and 40 are folded down at hinges 50 so that they lie perpendicular to the plane defined by upper plate 20. Flanges 38 and 48 are visible and engage with side wall 24. In FIG. 3, flanges 36 and 46 are also visible; here, flanges 36 and 38 engage side walls 22 and 24 respectively at first end 14 of main body 12 while flanges 46 and 48 at second end 16 of main body 12 do not engage the side walls. Flanges 36, 38, 46, and 48, when engaged with side walls 22 and 24 serve to hold the side walls in place and prevent twisting or unintended movement of the main body.

As best seen in FIGS. 2 and 4, end flaps 30 and 40 define end width EW which is greater than or equal to upper plate width PW. In addition, end flaps 30 and 40 define a centerline CL, which centerline CL is vertical when flaps 30 and 40 are folded in. Main body 12 is typically centered on vertical centerline CL.

As best seen in FIGS. 3 and 4, end flaps 30 and 40 may include predefined nail/screw holes 52. Predefined nail/screw holes 52 such as those in FIGS. 3 and 4 facilitate installment of support bracket 10 as they show the installer the best position for fasteners (for example nails or screws). They also prevent the need to drill holes in the end flaps or to otherwise modify the end flaps to allow attachment of the end flaps to studs 502 and 506. Holes 52 may include any suitable shape configured to facilitate coupling of the end plate to the inner surface of a building stud by any suitable fastener.

As mentioned above, hinges 50 which connect end flaps 30 and 40 to main body 12 allow end flaps 30 and 40 to pivot relative to main body 12 and thus allow for some variation in spacing between studs 502 and 506 to which panel wire support 10 is affixed. End flaps 30 and 40 may tilt in an outward direction (in the direction shown by the end flaps in FIGS. 4, 5, and 9, and by end flap 40 in FIG. 3) or inwardly (as in FIGS. 2, 6, and 8, and end flap 30 in FIG. 3) as needed to span a greater or lesser expanse between two studs. Hinges 50 are also flexible to allow some compressibility of the support bracket such that a folded configuration of support bracket 10 (as in FIGS. 2 and 5) may be squeezed into a smaller expanse between two studs.

Many of predefined holes 18 in main body 12 are shaped to reliably hold specific types of wires, and the shape and/or ornamental features of each hole 18 helps an installer identify which hole 18 to use for a particular type of wire 510. For example, some of the holes (e.g. a plurality of elongated holes 18 a) are shaped to hold flat 2-wire and 3-wire cables, often known by the name of an outer sheathing, such as Romex cable. Wires inside Romex cable may be of different thicknesses, typically 12-gauge or 14-gauge. In some examples, elongated holes 18 a (best seen in FIG. 8) have a length LA of approximately ¾″ parallel to a long axis, a width SA of approximately ½″ parallel to a short axis, and two semicircular ends 70 connected to the straight edges 72 of the elongated predefined hole (this forms a shape similar to a rectangle where the short edges have been replaced by semi-circles). Holes 18 a with the described elongated shape have been found to work particularly well with, for example, Romex-type cable. Internal guide walls 60 extend downward from elongated hole 18 a, and taper inwardly so that a reduced opening is formed having a reduced length of approximately ⅝″, a reduced width of approximately ⅜″, and curved ends connecting reduced straight edges in a shape similar to the original elongated hole. In some examples, elongated holes 18 a may be smaller or larger while retaining the same shape and/or the same ratios between dimensions.

This reduction in the size of the opening provides additional gripping ability and helps to prevent unwanted movement of the wire. The larger size of the opening at the top of the hole facilitates easier insertion of the wire into the hole by the installer. The edges of the opening at the top of the hole may include a bevel 74 or may otherwise be shaped to further facilitate the insertion of wires and to avoid sharp edges (this is particularly visible in FIG. 8). Guide walls 60 may be formed of flexible material to allow for some variation in the size of wires 510.

Some of holes 18 may be designed to hold other kinds of wires 510 and therefore may have other shapes. For example, FIGS. 2, 4, 10, and 11 show top views of a plurality of hexagonal holes 18 b or 218 b of a variety of sizes. In this embodiment, each hexagonal hole 18 b or 218 b may have a distance between opposite vertices measuring 1¼″, 1″, or ¾″. In some examples, hexagonal holes 18 b or 218 b may have various sizes. Similar to elongated holes 18 a for Romex wires, hexagonal holes 18 b or 218 b may have internal guide walls 60 that extend downward from the hexagonal hole. Guide walls 60 may taper inwardly so that a lower opening is formed having a hexagonal shape of a smaller size (for example 1⅛″, ⅞″, or ⅝″ between opposite vertices) than the hexagonal opening in upper plate 20. The hexagonal shape of holes 18 b or 218 b may be advantageous for wires having a round or cylindrical shape. Other shapes or sizes of holes and internal walls may be suitable for other embodiments intended to hold other types or sizes of cables and/or wires.

For each hole 18, internal guide walls 60 define a guide tube 76 for an individual cable or wire. This is best seen in FIG. 9. Guide walls 60 define a hole depth DH (see FIG. 7) that is less than or equal to vertical length of side walls VL. Firm, releasable grip is provided inside each guide tube by multiple features. For example, the guide tubes formed by guide walls 60 of each hole 18 help to keep wires 510 aligned for easy manipulation near and/or inside a main power panel. The tapered shape of hole 18 (also discussed above) facilitates insertion of the wire and provides additional gripping ability.

Furthermore, flexible support 62 may be formed by including at least two slits 78 in guide walls 60 (the hexagonal holes may have six slits, for example (see FIG. 9)). Still further, protrusion 64 may be preformed on flexible support 62 to increase the holding or gripping effect of flexible support 62 and to prevent the wire from moving in or out of or within the hole due to random or accidental movement of the wire. Releasability of the protrusion may be provided by tab 66, arranged so that a gap remains between tab 66 and any wire 510 that may be held by protrusion 64. As best seen in FIG. 18, an installer may grab tab 66 with a finger F, fingernail, or tool, as needed, and gently move a corresponding flexible support 62, and thus protrusion 64, away from a corresponding wire 510. Moving protrusion 64 away from the wire frees the wire for easy retraction or insertion. In the embodiment of FIGS. 2-9, protrusion 64 has a width of ⅛″ and tab 66 has a length of 3/16″. In some examples, protrusion 64 and tab 66 may have any suitable dimensions. Flexible support 62, protrusion 64, and tab 66 are best seen in FIGS. 9 and 18.

Second Embodiment FIGS. 10-12

FIGS. 10-12 show a second embodiment of the present invention. FIG. 10 is a top view of the second embodiment and FIG. 11 is a bottom view of the second embodiment. FIG. 12 is a bottom perspective view of the second embodiment that shows the side walls and the end flaps. The primary difference between the first and second embodiments of the present invention is the use of a different configuration of holes 18. Different configurations of holes 18 (such as the first and second embodiments of this invention but also including any other suitable configuration of holes 18) or different shapes of individual holes 18 (such as 18 a and 18 b but also including any other suitable size or shape of hole) may be advantageous depending on the particular application of the invention and what kinds of wires 510 or type of electrical panel 520 is in use.

FIG. 10 shows a top view diagram of a second embodiment of the invention. A support bracket 210 has a main body 212 with a first end 214 and a second end 216. Main body 212 is comprised of an upper plate 220, two side walls 222 and 224 (visible in FIG. 12) and a plurality of holes 218. Side walls 222 and 224 define a vertical length VL′. In this embodiment, VL′ is approximately 1½″. In some examples, VL′ may be any suitable length. Two end flaps 230 and 240 are hingedly connected to upper plate 220 by two hinges 250 (see FIG. 17) and have an end width EW′ (FIG. 12) and a vertical centerline CL′. Main body 212 is centered on vertical centerline CL′ and has an upper plate width PW′ which is less than or equal to end width EW′. In this embodiment, PW′ is 1½″. In some examples, PW′ may be any suitable width.

FIG. 11 is a bottom view of the second embodiment shown in FIG. 10.

FIG. 12 is a bottom perspective view of the embodiment of FIGS. 10 and 11. Here side walls 222 and 224 are visible, as are end flaps 230 and 240.

End flap 230 is hingedly attached to main body 212 by hinge 250. End flap 230 has a stud face 232 which is generally flat and a support face 234 which is generally parallel to and opposite stud face 232. End flap 240 is preferably shaped substantially identically to end flap 230 and is hingedly attached to main body 212 by hinge 250. End flap 240 has a stud face 242 which is generally flat and a support face 244 which is generally parallel to and opposite stud face 242. Support face 234 of end flap 230 and stud face 242 of end flap 240 are visible in FIG. 12.

As mentioned with respect to the first embodiment (support bracket 10), hinges 250 between end flaps 230 and 240 and main body 212 allow end flaps 230 and 240 to pivot relative to main body 212 and thus to allow for some variation in spacing between the studs to which panel wire support bracket 210 is affixed. End flaps 230 and 240 may tilt outwardly or inwardly (as in FIGS. 10-12) as needed to span a greater or lesser expanse between two studs. Hinges 250, like hinges 50, are flexible to allow for some compressibility so that a folded configuration of support bracket 210 (as best seen in FIG. 12) may be squeezed into a smaller expanse between two studs. As an example of the flexible hinge accommodating variation in the spacing between two studs, studs are typically spaced at about 16″ on center, leaving a nominal space between stud faces of about 14½″ (for 1½″-wide studs). The flexible hinge typically allows installation in between stud inner faces that are at least about 14½″ apart as well as between faces that are no more than about 14¼″ apart.

Many of predefined holes 218 in main body 212 are shaped to reliably hold specific types of wires and the shape and/or ornamental features of each hole 218 helps an installer identify which hole 218 to use for a wire 510 having a particular type or shape. Similar to what is shown for support bracket 10, support bracket 210 primarily has holes of two particular shapes: a plurality of elongated holes 218 a similar to holes 18 a which are designed to hold Romex cable of various gauges and a plurality of hexagonal holes 218 b similar to holes 18 b which are designed to hold round or cylindrical cables.

Holes 218 are tapered similarly to what was described above for holes 18 in support bracket 10; the reduction in size of the lower opening relative to the upper opening provides additional gripping ability and therefore helps to prevent unwanted movement of the wire. The larger size of the upper opening also facilitates easier insertion of the wire into the hole by the installer. A plurality of guide walls 260 may be formed of flexible material to allow for some variation in the size of wire 510.

Guide walls 260 define a guide tube 276 for wire 218 (see FIG. 12). Guide walls 260 define a hole depth DH′ that is less than or equal to vertical length of side walls VL′ (see FIG. 14). Firm, releasable grip is provided inside each guide tube by the multiple features described above in reference to holes 18. In particular, as in the first embodiment, guide walls 260 may include a flexible support 262. Flexible support 262 may include a protrusion 264 and a tab 266. Manipulation of tab 266 moves flexible support 262 and thus protrusion 264, in a manner similar to that shown for the embodiment of FIGS. 2-9 in FIG. 18. Movement of protrusion 266 allows or disallows unobstructed passage of the wire through the hole. In this embodiment, protrusion 264 has a width of ⅛″ and tab 266 has a length of 3/16″. In some examples, protrusion 264 and tab 266 may have any suitable dimensions.
